FEEDING MECHANISM FOR ROLLlNG--M|LLS.

S$IPEGIFIOATION forming part of Letters Patent No. 740,418, datedOctober 6, 1903.

I Application filed July 3, 1903. Serial lio. 164.132. (No model.)

To aZZ' whom it may concern.-

Be it known" that I, JEROME R. GEORGE, a citizen of the United States,residing at Worcester, in the county of Worcester and Commonwealth ofMassachusetts, have in vented a new and useful Improvement in a FeedingMechanism for Rolling-Mills, of

which the following is a specification, accom panied by drawings forminga part of the same, in which- Figure 1 represents a plan view of myimproved feeding mechanism for rolling-mills, representing aroll-housing shown in horizontal sectional view on the plane of thepasses between the rolls; and Fig. 2 is a side view shown in section online 2 2, Fig. 1.

Similar reference figures refer to similar parts in the different views.

The object of my invention is to provide a feeding mechanism by whichheated billets may be delivered from the delivery-opening of a furnaceto a pair of rolls having two operative sets of circumferential groovesor passes, by which the billet is directed into either one of the twosets of passes at the will of the operator, and the feeding mechanismembodying my invention is an improvement upon the feeding mechanismdesigned for a similar purpose and shown and described in United StatesLetters Patent No. 653,507, granted to Victor E. Edwards July 10, 1900.

Referring to the accompanying drawings, 1 denotes a billet-heatingfurnace having a mouth or opening 2, through which the heated billetsare withdrawn by an endwise movement upon a supporting-table 3, fromwhich they are fed to a pair of rolls 4, journaled in a housing 5 andhaving a pair of operative passes or circumferential grooves 6 and 7 towhich the heated billets are'longitudinally fed.

In the presentinstance the rollsare provided with other grooves 8 and 9,which may be brought into operative position by changing-the rolls endfor end; but for the purpose of the present illustration only grooves 6and 7 are to be considered. Arranged in front of the rolls areguide-plates 10, 11, and 12, between which are the passage-ways 13 and14, through which the billets are conducted to the grooves 6 and 7. Thepassageways 13 and 14 are provided with the flaring months 15 and 16,intowhich the heated billets are conducted by the attendant from thetable 3, or in lieu of the guide-plates 10, 11,

and 12 the delivery end of the table 3 may be brought sufficiently neartothe passes of the rolls to enable the billets to be delivered directlyfrom the table to the rolls. One corner of the table 3 is cutaway toprovide space for a plate 17, having its upper surface normally in thesame plane as the surface of the table 3 and provided on one side withan upwardly-projecting flange ,18 and having a portion 19 of the sideopposite the flange 18 arranged obliquely to the line of motion of thebillet as it passes across the plate 17 into the pass 7 of the rolls,The remaining portion of the opposite side of the plate 17' is providedwith a raised flange 20,- between which and the flange 18 a billet maypass from the table 3 across the plate 17 and be conducted to the pass 7of the rolls. The table 3 is .provided with a diagonal opening 21,through which a plate 22 projects upwardly above the surface of thetable 3 and serves as a guide to deflect a billet, whichmay belongitudinally pushed or otherwise moved across the table, sulficientspace being left between the flange l8 and the end' '23 of the obliqueplate to permit the passage of the billet across the plate 17. The plate22 extends downwardly beneath the table 3 and is hinged at one endbeneath the table to a bracket 24. The free end of the plate is providedwith a curved arm 25,: connected by a wire rope 26 with lifting means(not shown) for raising the plate 22 to bring its upper edge above thetable 3. The plate 17 is likewise pivoted by arms 27 27 to brackets 28at the opposite side of the table 3, and the plate 17 is which may beconnected by a wire rope 30 with lifting means (not shown) for raising 9the plate 17. In the drawings the vertical likewise provided with an arm29,

the plate 17 between the flanges 18 and 20 to the pass 7 of the rolls.If it is desired to push a billet forward and conduct the same to thepass 6 of the rolls, the vertical plate 22 is lowered to bring its upperedge below the surface of the table 3, and the plate 17 is raised abovethe surface of the table 3, so

that its oblique side 19 will serve as a guide to deflect a billettoward and in line with the pass 6 of the rolls. The table 3 is alsoprovided with an upwardly-projecting flange 31, placed at an oppositeinclination to that of the side 19 of the plate 17, so that the plate 17and flange 31 constitute flaring guides, between which the billet isconducted into alinement with the pass 6 of the rolls.

The operation of my feeding mechanism is as follows: Assuming the plate17 to be lowered to a level with the table 3, the vertical plate 22 tobe raised above the table 3, as shown in the drawings, a heated billetis pushed from behind through the mouth 2 of the furnace upon the table3. If its advancing end strikes the plate 22, it will be deflected andmade to enter between the free end 23 of the plate and the flange 18,passing over the plate 17 through the space between the flange 18 andthe flange 20 into the pass 7 of the rolls. The plate 22 is thenlowered, the plate 17 raised, and a second billet can be pushed forwardbetween the raised plate 17 and the flange 31 in alinement with the pass6 of the rolls. In case it becomes necessary that the second billetshould cross the path of the first entered billetbefore the latter hasbeen drawn 01f the table 3 this can be accomplished, as the raising ofthe plate 17 lifts the first entered billet sufficiently high above theplane of the table 3 to allow the second billet to pass beneath it andin contact with the inclined edge 19 0f the plate 17, space beingprovided therefor by the lifting of the first billet due to theelevation of the plate 17, and any tendency to displace the firstentered billet will be resisted by the flanges 18 and 20, betweenwhichthe billet will be held in proper alinement with the pass 7 of therolls.

What I claim as my invention, and desire to'secure by Letters Patent,is-

1. The combination withapair of rolls having two sets of circumferentialgrooves forming passes for a billet, and a billet-supporting table infront of said rolls, of a verticallymovable plate normally held in theplane of the supporting-table, raised flanges onsaid movable platebetween which a billet is conducted to one of the-passes in said rolls,and a vertically-movable guide-plate by which the advancing end of abillet is deflected upon said movable plate, substantially as described.

2. The combination with a pair of rolls, having two separate passes fora billet and a billet-supporting table in front of said rolls, of amovable plate capable of being raised from a position flush with thetable to one above said table, and having one of its edges oblique tothe line of motion of a billet across said table, a vertically-movingoblique guideplate moving in an opening in said table and a fixed guideon said table opposite said verticallymovable plate, substantially asdescribed.

3. The combination with a pair of rolls having two separate passes and abillet-supporting table in front of said rolls, of a plate capable of avertical movement from a position flush with the table to one above thetable, a raised guiding-flange on saidplate by which a billet isdirected into one of said roll-passes, a guide for directing abilletacross said plate, said guide being capable of being depressed below thesurface of the table, and a fixed guide on said table whereby a billetis directed into the other of said passes in the rolls, substantially asdescribed.
